WATER CHARACTERISTICS INLET "B"
To guarantee correct appliance operation, several water
treatment systems may have to be installed. For that purpose,
see the instructions of the following Flow Chart :

Make sure the dynamic
pressure is between
150 and 450 kPa
(1.5-4.5 bar / 22-65 psi)
* If deemed suitable by the installer, the water softener can be
replaced with a NANOFILTER.
ATTENTION:
- The periodical check of fi lter functionality, according to that
indicated by the manufacturer, is important to avoid compromising
appliance operation and to prevent the risk of corrosion.
- For good operation of the water softeners and fi lters make sure
to regularly service them.
Note: The softener (Automatic Water Softener) with automatic
regeneration has a kit (Resin Sterilizer) for sterilization of the
resins (additional request).
- To prevent damaging the appliance, at every periodical
regeneration do a fi lter wash cycle without introducing water in
the oven.
- The manufacturer declines any liability in case of incorrect
maintenance.
Attention:
Dispensers of substances for preventing scale in
the pipes (e.g. polyphosphate dispensers) must
not be used because they can compromise correct
appliance operation.

CHECK SUPPLY PRESSURE INPUT "B" AND "N"
The pressure measured upstream of the oven (and downstream of
any WATER FILTRATION SYSTEMS installed) must be between
150 and 450 kPa (1.5 - 4.5 bar / 22-65 psi) measured in dynamic
conditions, i.e. during the washing phase.
